In this article, the electrophysical properties of Ni/SiO₂/n-Si metal-oxide-semiconductor (MOS) structures formed on n-type monocrystalline silicon substrates in the [111], [110], and [100] crystallographic orientations have been investigated. The study determined the influence of a thin tunnel oxide layer (2–4 nm) formed on the surface of the semiconductor monocrystalline substrate on the Schottky barrier parameters depending on the crystallographic orientation by analyzing their current-voltage characteristics (I-V). Based on the experimental results, energy band diagrams of the MOS structures were constructed, taking into account the interface states at the SiO₂/Si boundary. It was found that the Schottky barrier height changes depending on the crystallographic orientation of the substrate surface as φB[111] > φB[100] > φB[110]. The obtained results serve as a scientific basis for designing optimal parameters of microelectronic sensors and photoelectric converters with high sensitivity and selectivity.
